The field trip will cover the Permo-Triassic CFB, with stops along the lesser deformed western branch on the first day, across the syntaxis and then along the stronger deformed, northerly overturned southern branch.
On the first day, we will initially follow the N7 and turn towards the east into the Cederberg Mountains between Citrusdal and Clanwilliam, then drive south to overnight at Mount Cedar.
The second day will be spent to view the relationships between folds of the western branch and the southern branch in the syntaxis between Ceres and Montagu. Stops are scheduled to discuss flexural slip fold interference and syntaxial structure, the Mesozoic Worcester fault, seismicity and hot springs.
On the third day, we travel into the southern branch via R62 from Montagu to Oudtshoorn to see northward overturning, kink folds, cleavage, Miocene geomorphology, and the hot spring at Warmwaterberg, the Mesozoic rift fill sequence and the Kango fault.
The fourth day will be spent travelling to Willowmore, stopping to view Holocene fault reactivation along the Kango fault system, Cretaceous rocks of the Oudtshoorn Basin, the inlier of basement rocks (Kango Group). Folding is spectacularly displayed in sections at Meiringspoort, whereas low angle faulting will be viewed at Uniondale.
On the fifth day we travel via Steytlerville to overnight in Port Elizabeth. Folded and thrust-faulted rocks of the upper Cape Supergroup will be examined and we cross the Algoa Basin (Cretaceous) at Uitenhage on the way.
On the final day of the excursion we will drive back from Port Elizabeth to Cape Town and experience the spectacular scenery along the Garden Route.
